Product Description

Audio Precision APx555 B Series Audio Analyzer

The Audio Precision APx555 B Series is the world highest performance audio analyzer, delivering industry-leading residual THD+N of typically below -120 dB. Designed for the most demanding audio research, development, and production test applications, it sets the benchmark for precision audio measurement.

Key Features

• Ultra-Low THD+N: Typically less than -120 dB (22 kHz BW) at 2-9 Vrms, the best in the industry
• High Performance Sine Generator: 5 Hz to 204.75 kHz with exceptionally stable RC oscillator
• Dual Sine & Var Phase: 24-bit Sigma-Delta DACs at 192 kS/s for multi-tone testing
• 2 Independent Channels: Simultaneous dual-channel generation and analysis
• Wide Amplitude Range: 0 to 26.66 Vrms balanced (75.4 Vpp)
• Exceptional Flatness: +/-0.008 dB from 5 Hz to 20 kHz

Analog Generator

• Waveforms: High Performance Sine, Dual Sine, Variable Phase Sine, Burst Sine, IMD, Noise, Square, Multitone, and Wave File Playback
• IMD Test Signals: SMPTE, MOD, DFD, and DIM modes for comprehensive distortion analysis
• Output Impedance: Selectable 40 Ohm, 100 Ohm, 150 Ohm, 200 Ohm, or 600 Ohm (balanced)
• ADC Test Signal: Optional software license for analog-to-digital converter characterization
